Anybody have any luck with this yet?  Same issue, just on a 7368.  Laptop last night seemed to be doing some updates on its own. went to restart today and got that error message.

I have exactly the same message on am Inspiron 5559. As above everything else was fine. Critical battery notification, an automated hardware check ran and then the above message is displayed.

I tried everything including a recovery disk and nothing worked. Spent 2 hours on the phone with dell and finally had to send it in for repair. They replaced the hard drive and reinstalled windows 10. Lost all of my files. I read that the automatic windows updates for 10 bricks the system.

This works, however everything I reboot my laptop. I will have to repeat the steps again.

Any one has a solution to fix that?

As a workaround, try to disable Secure Boot.
